A sudden twist leaves a player unable to continue and holding a knee. That physical harm is an injury. Sports injuries range from minor bruises to season-ending structural damage.

Acute injuries occur in a single event—sprains, strains, fractures, dislocations. Overuse injuries develop gradually from repetitive stress—tendinopathies, stress fractures, certain muscle imbalances. Contact, landing mechanics, fatigue, and inadequate recovery all contribute to risk.

Immediate management follows established first-aid principles. Accurate diagnosis guides treatment and the timeline for return. Rehabilitation restores capacity before full competition resumes. Prevention programs targeting strength, neuromuscular control, and load management reduce incidence in many sports. Every athlete eventually confronts injury; the quality of response shapes the length of the career.

The best injury is the one that never happens, but preparation for those that do is essential.
